The upper end of the telescopic column 407 is connected to a first rotating block 413 for adjusting the angle of the spraying mechanism. The first rotating block 413 is connected to the spraying mechanism through a second rotating block 417. The spraying mechanism includes a water supply column 5 fixed to a second connecting block. A plurality of spray pipes 6 that can slide and expand are connected to the side wall of the water supply column 5 to adjust the length of the spraying range. For example, Figure 4 , Figure 5 As shown in the figure, the spray pipes 6 can be folded and stored between them, greatly reducing the size after folding. A storage box 201 is provided above the water tank 2. The second rotating block 417 can drive the spraying mechanism to rotate downward and descend into the storage box 201.

[0019] A battery box 3 is provided at the upper end of the towing vehicle 1. A protective cover 301 is provided at the upper end of the battery box 3. A control panel 302 is provided inside the protective cover 301. For example, Figure 11 , Figure 12 As shown in the figure, one side of the support column 401 is an open structure. A guide column 402 and a first threaded rod 403 are provided inside the support column 401.

A threaded hole 408 that cooperates with the second threaded column is provided inside the telescopic column 407. The height adjustment is completed through two-stage lifting of the lifting column 406 and the telescopic column 407. A support plate 411 is provided at the upper end of the telescopic column 407. The first rotating block 413 is located at the upper end of the support plate 411. A third motor 412 for driving the first rotating block 413 to rotate is provided at the lower end of the support plate 411. The rotation of the first rotating block 413 can drive the spraying mechanism to achieve a 360° rotation in the horizontal direction, realizing the change of the spraying direction. A turntable 415 is connected to the side wall of the second rotating block 417. A fourth motor 414 for driving the turntable 415 is provided inside the second rotating block 417. For example, Figure 13 As shown in the figure, one end of the second rotating block 417 is connected to the turntable 415 through a connecting plate 416. The second rotating block 417 can drive the spraying mechanism to rotate downward for storage.

[0020] For example, Figure 3As shown, the other end of the second rotating block 417 is detachably connected to the water supply column 5, that is, the spraying mechanism can be disassembled for use, and at the same time, it is convenient for the maintenance of the spraying mechanism.

[0021] A hook 509 is provided at the upper end of the water supply column 5. When the spraying mechanism is disassembled for use, the spraying mechanism can be suspended at a high place by means of the hook 509.

[0022] As Figure 13 shown, an insertion post 418 is provided at the end of the second rotating block 417. A stop block 419 is provided on the side wall of the insertion post 418. A guide sleeve 421 is provided on the side wall of the second rotating block 417. A stop rod 422 is provided in the guide sleeve 421. An anti-detachment block 420 is provided at one end of the stop rod 422. A handle 423 and a card slot 424 are provided at the other end of the stop rod 422. As Figure 6 shown, a connection hole 503 that cooperates with the insertion post 418 and a hook 501 that cooperates with the card slot 424 are provided on the side wall of the water supply column 5. A relief groove 504 for installing the stop block 419 is provided on the side wall of the connection hole 503. A stop groove 505 that cooperates with the stop block 419 is provided on the inner wall of the relief groove 504. One end of the hook 501 is connected to the water supply column 5 through a rotating shaft. A torsion spring is connected between the hook 501 and the water supply column 5. A support block 502 for supporting the hook 501 is provided on the side wall of the water supply column 5. The support block 502 keeps the hook 501 in a horizontal state.

[0023] During connection, the insertion post 418 cooperates with the connection hole 503, and the stop block 419 cooperates with the relief groove 504. Then rotate the water supply column 5 to make the stop block 419 rotate into the stop groove 505. Then slide the stop rod 422 through the handle 423. The stop rod 422 is close to the side wall of the water supply column 5. The stop rod 422 pushes the hook 501 to rotate upward. After the stop rod 422 is fully opened, the hook 501 cooperates with the card slot 424 under the action of the torsion spring to pull the stop rod 422, realizing the installation and fixation of the water supply column 5 and the second rotating block 417. During disassembly, open the hook 501 upward, open the stop rod 422, rotate the water supply column 5, and take out the insertion block.

[0024] As Figure 7 shown, a water inlet nozzle 506 connected to the water pump 202 through a hose is provided at the lower end of the water supply column 5. A docking hole 508 connected to the spray pipe 6 is provided on the side wall at the upper end of the water supply column 5. A water supply hole 507 connecting the water inlet nozzle 506 and the docking hole 508 is provided in the water supply column 5.

[0025] As Figure 9 shown, water inlet holes 606 and water outlet holes 609 are provided at both ends of the spray pipe 6. A sealing block 604 is sleeved outside the water inlet hole 606. A sealing ring 605 is provided on the side wall of the sealing block 604. First limit blocks 607 and second limit blocks 608 are provided at both ends of the spray pipe 6. As Figure 8As shown, a chute 602 is provided on the side wall of the spray pipe 6, and sliders 603 that cooperate with the chute 602 are connected to both sides of the water inlet hole 606. As Figure 10 shown, adjacent spray pipes 6 are connected by the cooperation of the sliders 603 and the chute 602, and a spray head 601 is connected to the end of the spray pipe 6. When in use, the water inlet holes 606 between two spray pipes 6 are butted against the water outlet holes 609, and at the same time, the fixation between the two spray pipes 6 is achieved under the elastic extrusion of the sealing block 604. At the same time, in order to improve the firmness when opening, the first limiting block 607 and the second limiting block 608 adopt magnets. After opening and closing, the sliders 603 are further fixed by magnetic adsorption.

[0026] Two rows of spray pipes 6 are arranged on each side of the water supply column 5. The spray heads 601 of the upper spray pipes 6 face upward, and the spray heads 601 of the lower spray pipes 6 face downward. The upper and lower spray pipes 6 are connected by a synchronous rod. The spray heads 601 are atomizing spray heads 601, realizing upper and lower spraying, increasing the spraying area and water volume, and improving the dust suppression effect. At the same time, according to the actual use situation, the number of spray pipes 6 can be increased or decreased. The first limiting block or the second limiting block can be removed to increase or decrease the spray pipes 6. The water outlet holes of the spray pipes at the outermost ends need to be blocked.

[0027] As Figure 14 shown, when in use, the device can be arranged along the perimeter of the construction area. After use, the spray pipes 6 are slid towards the water supply column 5, and the water supply pipes on each side are arranged side by side for storage. The second rotating block 417 drives the spraying mechanism to rotate downward, and then the column 4 descends, so that the spraying mechanism extends into the storage box 201 for storage, greatly reducing the overall size of the device and facilitating storage and transportation.

[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
